ALSA: hda-intel - remove model=hwio , use probe_only=3 instead

The probe_only module parameter skips the codec initialization, too.
Remove the model=hwio code and use second bit in probe_only to
skip the HDA codec reset procedure.

 information before modified by the driver.  Of course, the driver
 isn't usable with `probe_only=1`.  But you can continue the
 configuration via hwdep sysfs file if hda-reconfig option is enabled.
+Using `probe_only` mask 2 skips the reset of HDA codecs (use
+`probe_only=3` as module option). The hwdep interface can be used
+to determine the BIOS codec initialization.
